Similarly, increased knee adduction moments in the affected limb may indicate unresolved biomechanical deficits. These findings suggest that the elite population may not be fully prepared to resume high-level activity within the 6-month time frame outlined in current rehabilitation protocols. A longer recovery period may be necessary to restore joint kinematics and kinetics to levels more consistent with a safe return to sport.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/23259671251340302","type":"journal-article","created":{"date-parts":[[2025,5,27]],"date-time":"2025-05-27T11:50:36Z","timestamp":1748346636000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Biomechanical Analysis After Anterior Cruciate Ligament Reconstruction at the Return-to-Sport Time Point"],"prefix":"10.1177","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3826-0292","authenticated-orcid":false,"given":"Saud M.","family":"Alarifi","sequence":"first","affiliation":[{"name":"Rehabilitation Center, Riyadh First Health Cluster, Ministry of Health, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lee C.","family":"Herrington","sequence":"additional","affiliation":[{"name":"Centre for Health, Sport and Rehabilitation Sciences, University of Salford, Salford, England, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Omar W.","family":"Althomali","sequence":"additional","affiliation":[{"name":"Department of Physiotherapy, College of Applied Medical Sciences, University of Ha'il, Ha\u2019il, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Faisal","family":"Alenezi","sequence":"additional","affiliation":[{"name":"Therapeutic Deputyship, Saudi Ministry of Health, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bodor","family":"Bin Sheeha","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Sciences, College of Health and Rehabilitation Sciences, Princess Nourah bint Abdulrahman University, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard K.","family":"Jones","sequence":"additional","affiliation":[{"name":"Human Movement and Rehabilitation, School of Health and Society, University of Salford, Salford, UK"},{"name":"The Manchester Institute of Health and Performance, Manchester, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,5,27]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.2519\/jospt.2012.3871"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2013-093398"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546511422999"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.asmart.2018.11.004"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2011.09.009"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbmt.2024.01.022"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199072060-00012"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546509337934"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.2008.052522"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.gaitpost.2004.01.010"},{"key":"e_1_3_3_12_2","volume-title":"Statistical Power Analysis for the Behavioural Science","author":"Cohen J","year":"1988","unstructured":"Cohen J.
